PATENT oFFIoE WATE Ft-C OQLER. f

v T 0 all whom, it pea/y concerm' States, residing at Indianapolis,inthe county of Marion and State of Indiana, have invented certain new anduseful Improvements in Water-Coolers, of which the following is aspecification.

This invention relates to improvements in apparatus for cooling water,and is here shown as ap water used surrounding the parts of anexplosive-engine that become commonly heated during the operations ofsuch engines aii'd in the drawings is shown as used for cooling thegasoleneengine of"an" autom'obil ebut it is not desired to limit itft'oai'itoriiobile construction nor to engine construction. It is desired toinclude all uses to which the invention-is applicable. I j

The object of the invention'is' to conduct the heated water throughconduits which will havethe largest obtainable'surface exposed to theair'for the purpose of cooling the water'contained within said conduits.

A further object of the invention is to provide a simple, compact,durable,- and inexpensive apparatus and one that be easy to operate and.to keep in repair.

We accomplish the objects of our invention the mechanism illustrated inthe accompanying drawings, in which- F ure 1 is a perspective view of anautomob e, provided with our improved watercoolin apv aratus; --Fig. 2is a front elevation 0 sai apparatus.

air-tube passing therethrough, the'walls' of which are funnel-shaped.Fig. 11 is a detail showing one of the cooling-pipes on a larger scalethan the other figures of the drawings, the view being in verticalsection on the line 11 11 of Fig. 12, andFig. 12 is avertical s-ec-.

tion on the line-12 12 of Fig. 11.

Like characters of reference indicate like parts throughout the severalviews of the draw ngs.

Referring to the drawings, 10 is thebase of our cooling apparatus, andis here shown as a rectangular sheet-metal box, with a sheetme'tal cover14, preferably of copper. This box is divided into two compartments 11and 12 by means ofthe partition 1?, which 4: prevents directcommunication I between.

As shown in Fig. 5, the.

said compartments.

sheet-metal cover 14 is provided with. a

lar e number of perforations 16, each of which are long and narrow, asshown, and

are arranged in a series of staggered rows. u A tube 17, one for eachopen1ng,'is secured in said water-tight joint with plate 14.. Theseperforations in a manner to provide a' tubes 17 are flattened, as shownin Fig. 6, so

that the opening through them presents a long and narrow space forpurposeswhich will be hereinafter explained. The plate 14, which formsthe cover to the above-described box, main portion of the portion inwhich the tubes 17' his portion includes the side plates 18, whichsupport the top metal form ,withtheir related parts, tubes 17, which isopen at rear. 14 is a second frame 19, which gives strength,

and rigidity to the construction; This.

frame 19 has the dowel-pins 20, which pins are provided with transverseslots in aliuemerit, for the several pins to receive a key,

.which will be driven therein after the parts,

are assembled for the purpose of looking together and securing saidparts;

frame 19 ,and, a casing foijfthe. both front. and-. 3.; Between thebottom box and its cover also forms the bottom of the central orwater-cooler, being that are located-1 Supported upon the top frame 19isthe cap 23;,which has a top, as shown as curved in the drawingabutwhich maybe of any desired'shape and is closed at front dowel-pins 20previously i described, which sameurpose. 27"is a metal plate,

p a nd'back to form a water-tighthollow structure. This.

cap will have dowel-pins 25, similar to the. a

. suitable, removable closure.

23 and top frame 19, so as to form a gasket to make a tight oint betweenthe parts. The flattened tubes 17 will pass through this plate 27 andwill make a water-tight joint therewith. The open ends of tubes 17 will-communicate at their tops with the interior partments of cap23 is thepipe 33, which is perforated at frequent intervals throughout itslength, and connecting with said pipe 33 is the pipe 37, which isconnected with the wateracket of a gasolene-engine or any other sizipplyfrom which water isobtained in a heate condition and which is to becooled. This water entering through pipe 37 is discharged through theperforations in pipe 33 into the hollow interior of cap 23 and iscarried through tubes 17 down into the compart-. ments 11 and 12 in theb )x at the base.

39 is a pipe which takes from compartment 12 and discharges the cooledwater backinto the Water-jacket of the engine or whatever is to besupplied. The purpose of the partitions 13 and 31 is to divide theirrespective vessels into coinpartmen s, which will prevent the flow ofthe water longitudinally of said vessels, thereby compelling it topassback and forth on a longer travel through the series of coolingtubes 17.Thus water supplied through tube 37 will pass down into compartment 11through those tubes 17 that have their inlets between the partition 31and adjacent end of the cap 23, and, the water from compartment 11 willpass up to the 'cap on the other side of partition 31 through thosetubes 17 that have their inlets between the mouths of the first set anda partition 13,

'l and the water thus delivered to the cap 23 from the' cap into thecompartment 12,v 5,

and

through said tubes 17 is carried'down again through the tubes 17, thathave their discharge-openings into said compartment 12,

our the atter compartment the water which has been thus subjected to thecooling action of the air bathing the outside of the tubes 17 is carriedoff for use through pipe 39. By flattening the tubes, as shown andpreviously described, a very thin column of water is carried throughthem, and this column is exposed to the largest possible cooling actionof the air passing or surrounding said tube. In order to retard the flowof the water through tubes 17, their discharge ends may be contracted bypressing their walls closer together, as shown in Fig. 8.

42 are a series of pipes extending trans- 'water-discharge pipe takingwater versely through the cap 23 and the compartments 11 and 120i thebase. These pipes are open to atmosphere at both ends and provideair-conduits through their respective chambers for the cooling of thewater contained in said chambers by the flow of air through said pipes42. r

47 represents a tubular opening through the base for the insertion ofthe startingcrank of an automobile and has nothing whatever to do withthe operation'of our cooler proper.

Our invention is capable of various modifi cations and variations inconstruction with out departing from the spirit of the invention, and wedo not therefore desire-to limit our selves to the exact constructionshown, nor do we desire to be understood as limiting our invention toautomobiles or to the cooling of explosive-engines;but i What we'doclaim as new; and wish to see cure by Letters Patent of the UnitedStates,-

1. In a cooling apparatus, two or more chambers, and a plurality oftubes forming communications between said chambers, said tubes beingcontracted in oneidiameter to vform passages of greater length incrosssection than width and said tubes being additionally contracted onthe same diameters at their discharge ends.

2. In a cooling apparatus, chambers remote from each other, and tubesconnecting 'said chambers, said tubes being of greater length than widthin cross-section and hav- 10o ing those sides which are in closestrelation to each other throughoutthe main portion of the tube closertogether at their discharge ends than at any other portions of therespective tubes. y

3. In a cooling apparatus, a plurality of chambers. having transversefunnel-shaped. air-tubes passingtherethrough, a plurality of. tubesconnecting the chambers with each other, said tubes being long andnarrow in cross-section. 4. A cooling apparatus'having a plurality ofcooling-tubes which are lon and narrow in cross-section and are stillfurther restricted ,at their discharge ends by a closer approach 11 5 ofthose walls which are the nearest to each other throughout the bodies ofthe tubes.

5. A cooling apparatus having a plurality of cooling-tubes whichare longand narrow in cross-section the walls of which at the sides of the tube,are brought still closer together at their discharge end. i

6. In a water-cooler, a hollow base divided by partitions intocompartments, a hollow cap also divided by partitions into comparta 12'5ments, a water-supply pipe discharging into one'lof the compartments ofthe ca and a om one of the base compartments, and a plurality ofvertical tubes in a plurality of rows for each 1 a compartment,staggered with relation to each other in the several rows, said tubesforming conduits between the ca andbase compartments, said tubes beingattened on opposite sides to form conduits of greater length than widthin cross-section:

7. In a Water-cooler, a body portion 0 en at front andrear andcontaining a plura ity of cooling-tubes arranged in stag ered rows, eachof said tubes being long an narrow in cross-section, a hollow capreniovably secured u on said body portion with the interior 0 which saidcooling-tubes communicate, slotted dowel-pins entering the body from theca keys passing through the slots of the dowe ins to lock the cap to thebody and a hollow ase upon which said body portion is removably secured,and with the interior of which base said cooling-tubes communicate, anda supply-pipe to and a discharge-pipe from said apparatus.
